The art works proposed are examples of results of a yearly workshop for industrial design students at TU/e. The workshop serves to teach mathematical principles to design students. The students defined tessellations in mathematical formulas, using the Mathematica software. But we do not stop at a digital representation of their tessellation design, we continue to cut their tessellations in Perspex (using vector graphics output from Mathematica). It moves the abstract concepts of math into the real world, so that the students can experience them directly, which provides a tremendous reward to the students. The pedagogics of the approach has already been described in [Bartneck, Feijs, 2009]. Now we selected three of the most interesting works for the exhibition. Two are in Perspex where pieces of different colours have been glued together. The third work also includes wood. In our opinion the works are visually interesting and the material qualities add to the overall aesthetics.
